Be it known that I, GEORGES AIEX'ANDEE PHILIPPE BELLON, a citizen of theRepublic of France, residin at 3 Rue du Moulin,

Vincennes, Seine, rance, have invented cer,

tain new and useful Improvements in Torches, of which the following is aspeciication.

MyV present invention relates to torches, such `as are used inconnection with soldering and for various purposes where it is desiredto concentrate and emit a name in' a predetermined direction.

The principal objects of my inventionare to provide a device simple 'inconstruction, and inexpensive to manufacture, and one eicient in action,so that the flame may be .directed as desired without bodily moving thecontainers for the Huid, etc.

'A further object of my invention is to.

provide means whereby, after the torch has been lighted for a certainperiod, reignition of the fuel accidentally extinguished, takes place,so long as the fuel is conducted to the jet of the torch. I

In the drawings, forming a part of this specification: Figure 1 is aside elevation cfa torch embodying my invention. ig. 2 is a top planview of the same, parts being shown in central horizontal section todisclose details of construction. Fig. 3 is a detailed view iii-centralvertical section of the atomizer used in connection with the de vice.

The containers for water under pressure and inflammable fluid, aredesignated by a and b, respectively. Egress of water from container a iscontrolled by a two way valve c which supports a ball and socket jointe,- having a pivotal center as indicated atd. This joint supports anozzle n of the torch. The joint e is constructed, in any suitablemanner, to form a `conducting means between the conduit o, which iscoiled about the nozzle n, and the valve c. Conduit o leads to a lter m,which in turn is conductively connected with the atomizertj carried y bythenozzle n and disposed with its egress end Z directed to emit theluidintermixe therein, through said nozzle.

A pump p or other suitable device is pro vided by which to attain thedesired pressure in container a, a tube t leading from 'the pump p `tothe valve c which latter controls inlet of air to the container as wellas egress of the liquid therefrom. i

The container b, through conduit b', is adapted to deliver inflammableuid to the atomizer j, by entering the latter at port v. shown in Fig. 3of the drawing, a valve b" being interposed in said conduit'for thecontrol of the Huid.

Inasmuch' as the conduit b isexible, it will be perceived that auniversal joint, supporting the nozzle permits the latter to be Amovedto direct the concentrated flame in the desired direction.

:Preferably within nozzle n and centrally disposed to lie in or aboutthe path ofthe flame emitted by the atomizer j, or in other words, 'inthe path of concentration of nozzle n., I provide a cylindrical tubularmember f, preferably of pure nickel, or other metal fusible only at avery high temperature, which temperature the torch is not adapted toprovide. This cylindrical tubular member-is provided with perforations gto facilitate contraction and expansion of the tube, and so as not toexclude oxygen desirable to facilitate ignition, and the member ispreferably supported by a stem h secure to the nozzle n, and disposedwholly below the path of the flame.

The operation of the device is as follows In starting the device,assuming that there is thedesired pressure in container a, the valve cis operated so that air is per# .mitted to flow through coil o and inpassing port lc in atomizer j, the inflammable fluid -is drawn fromcontainer b and intermixed with the air. The carbureted fluid is thenignited and as soon as the nozzle n has attained the desiredtemperature, the valve c is operated to permit water to flow throughcoil o, which Water is transformed into steam, rby the heat and acts aspreviously described in connection with the air, to carry with itinflammable huid at the egress opening Z of the atomizer y'. As soon .asthe inflammable fluid is emitted from the-atomizer jand has been ignitedfor a period suiiicient to heat the cylindrical tubular member j to ahigh temperature, should the ignition of the fluid cease, due to acurrent of air, or otherwise, the fluidemitted from atom izer will bereignited owing to the high temperature which the member f has attained,because of its disposition in the flame 'concent-rated by the nozzle n.

It is to be noted that the stem h is so disposed that it is littleeffected by the heat,

an annular member, fusible at a very hightemperature, disposed in thepath of concentration, with its annular section at substantially rightangles to the axis of the path of concentration. 4

2. In a torch of the character described,

the combination of a nozzle, a device' adapted to deliver inilammablefluid through said nozzle to be concentrated thereby, and a cylindricaltubular member, fusible at a very high temperature, disposed in the pathof concentration, with its cross section at substantially right anglesto the axis of the path of concentration.

3. In a torch of the character described,

. the combination of a nozzle, a device adapted to deliver inflammablefluid through said nozzle to be concentrated thereby, and

a perforated cylindrical tubular inember,

fuslble at a very high temperature, disposed in the path ofconcentration, with its cross section at substantially right angles tothe axis of the path of concentration. 4. In a torch, of the characterdescribed, the combination of a nozzle, a :device adapted to emitinflammable luid through said nozzle to be concentrated thereby, anannular member fusible at a very high temperature, 4disposed in the pathof concentration with lts annular section at substantially right anglesto the axis of the path of concentration, and a stem secured to saidannular member and nozzle for supporting the former, said stem beingdisposed below the path of concentration, substantially as and for thepurpose set forth. l

In witness whereof I have hereunto set my hand in presence of twowitnesses.
